Abstract: A linkage mechanism includes: a base member; a first link rotatably connected to the base member, the first link defining a first arc-shaped guide groove centered on a pivot axis about which the first link rotates relative to the base member; a second link rotatably connected to the first link; a connecting member rotatably connected to the base member and the second link; an actuating mechanism including a linear actuator and a transmission member that is driven by the linear actuator, the transmission member having a first end rotatably connected to the output shaft, and a second end slidably received in the first arc-shaped guide groove. When the linear actuator drives the connecting member to extend and move, the second end of the transmission member abuts against one end of the first arc-shaped guide groove, which drives the first link to rotate relative to the base member.

Abstract: A servo includes a motor, an output shaft used to drive an external component and having an external lateral surface, a gear set arranged between the motor and the output shaft and used to transmit power from the motor to the output shaft. The gear set includes an output gear arranged around the output shaft. The output gear defines a through hole that allows the output shaft to pass therethrough. The through hole has an internal lateral surface facing the external lateral surface. The servo further includes a connection ring arranged around the output shaft between the external lateral surface and the internal lateral surface. The connection ring is used to connect the output gear to the output shaft when a load placed on the output shaft is less than a preset value, and disconnect the output gear from the output shaft when the load exceeds the preset value.

Abstract: A servo assembly includes a housing, a motor, a control circuit board and a gear transmission mechanism that are arranged in the housing. The motor is electrically connected with the control circuit board. The gear transmission mechanism is rotatably connected with a motor output shaft of the motor and the servo output shaft. A servo output shaft has one end that is received in the housing and located above the control circuit board and an opposite end that extends out of the housing. A servo plate is connected to the end of the servo output shaft which is away from the control circuit board. The servo plate includes a connecting portion connected with the servo output shaft. An annular member is disposed between an end surface of the connecting portion and the housing, and the annular member is used to limit an abnormal rotation of the servo output shaft.

Abstract: A dual-output-shaft servo includes a housing including two first sensors and two actuating mechanisms. Each actuating mechanism includes a motor assembly, a speed reduction mechanism opposite the motor assembly, and a transmission mechanism arranged between the motor assembly and the speed reduction mechanism. The speed reduction mechanism includes an output component, and a connection shaft is fixed to the output component. A first sensor counterpart is attached to an end of the connection shaft which faces the motor assembly. The transmission mechanism is to transmit mechanical power from the motor assembly to the speed reduction mechanism. The axes of rotation of the output components of the speed reduction mechanisms are skew or intersected with each other.
